Vodacom data UPgrade

On the 7th of February when I tried to login to my Vodacom portable router I was told "you are out of balance" (yes really, that's their terminology for "your data is finished/you have run out of data".)

Today I discovered that in September I was upgraded on a new 24-month contract. Here are the details of the UPgrade - I was paying the same price as now for 10gb +10gb night owl and with the UPgrade I am receiving 5gb + 5gb night owl. Some upgrade!

Apparently someone phoned me and I would have agreed the upgrade. I never even allow the telesales people more time than "Hello how are you, I am fine" - when I haven't even asked them nor do I care how they are - so how does Vodacom allow them to earn commission no doubt on bogus sales? If I hadn't been "out of balance" I may never have known about my UPgrade.

Meanwhile I have to wait 7 working days while my complaint is escalated to check if I am being honest or not. I wonder if the missing 5gb per month since September will be refunded. I am not holding my breath.
